Would you have said the same thing during the Cold War when nuclear weapons were proliferating? That’s the equivalent of what the developing offensive capabilities of models, basically cyber nukes. Or WMDs in general. OpenAI is accidentally hacking people, if someone made the decision to deliberately direct an agent swarm to attack national infrastructure you don’t think they could do much worse? Human extinction is a long shot but I wouldn’t say the same about a mass casualty event of some kind, and who knows what that might spark.
